The world's most haunted hotels

In the 20th century, Karosta Prison was used as a Nazi and Soviet military
prison. It's no wonder the transformed prison-themed hotel is said to
experience paranormal activity as thousands of prisoners allegedly died on
site. If staying in the hotel and being treated like a prisoner isn't
enough, the staff will tell guests stories about lightbulbs that unscrew
from their sockets, doors that open by themselves and the ghost of a woman
who hanged herself that wanders the corridors.
